AquaChek Copper 3-in-1 test strips

Tests for 3 important chemistries in seconds: Copper Ion, pH, and Total Alkalinity. AquaChek® Copper 3-in-1 test strips are designed for use with mineral purification or copper ionization systems. Simply dip the test strip into the pool or spa and compare to the color chart to verify if the levels are within the appropriate range. Get 3 important test results in just one dip! AquaChek® Copper 3-in-1 also measures pH and Total Alkalinity levels which helps guard against troublesome scale formation and/or corrosion that can occur with sudden changes in your water's pH. Maintaining proper levels will help ensure that bacteria and other contaminants are eliminated, leaving spa water clean and healthy. It is recommended that the water be tested before and after each use. If used in a pool we recommend testing at two ends or sides of the pool a minimum of twice a week. It's also a good idea to keep a log and track all test results.
